Abstract: A method, receiving device, network element, system and computer program product for controlling discontinuous reception at a receiving device of a communication network are disclosed. A regular discontinuous reception cycle of a discontinuous reception scheme is set, and this regular discontinuous reception cycle is switched to a shorter temporary discontinuous reception cycle or is switched off, in response to an event which triggers a reply of the communication network to the receiving device. Thereby, delays of network replies can be shortened or controlled in case discontinuous reception (DRX) cycles are implemented at the receiving device.

Abstract: A method of operating a mobile station in a WCDMA system. The mobile station has a rake receiver (90) having a plurality of demodulator fingers (71,72,73). One of the demodulator fingers monitors a neighbouring cell and other demodulator fingers monitor an assigned cell. When the mobile station is in an idle mode, if it is stationary, activity of the demodulator is reduced by switching off the demodulator finger which monitors the neighbouring cell.

Abstract: A cellular radio system comprises a multitude of base stations (101-106, 201-204, 211-212, 501-504) for offering a radio interface to mobile terminals (205, 215, 508). The radio interface is used for communicating general information to the mobile terminals and arranging for dedicated communication between a certain mobile terminal and the cellular radio system. For imposing restrictions to the operation of the mobile terminals on at least one isolated, geographically defined restricted area (107, 108, 200, 213) the system comprises a certain first base station arranged to transmit, similar to said general information, information about the nature of the restrictions applicable on said area to the mobile stations.

Abstract: A method is presented for implementing synchronization between the timing of a first telecommunication system and the timing of a second telecommunication system. A first counter value is regularly updated at a pace determined by the first telecommunication system and a second counter value is regularly updated at a pace determined by the second telecommunication system. At a first time instant the current first counter value is stored. At a second, later time instant the stored counter value is read. Using the read counter value an operational step is timed so that its timing in relation to the timing of the first telecommunication system is known.

Abstract: The transmission of control information from a base station to at least one mobile station in the cell of a cellular radio system takes place using a first channel and a second channel. At a first moment of time, there is an indication on the first channel about the location of the piece of control information on the second channel. At a second moment of time, later than said first moment, the piece of control information is transmitted on the second channel.

Abstract: The invention relates to internal measurement methods of mobile communication systems, more particularly how to arrange time intended for signal measurement for the mobile stations. In the method according to the invention the RSSI and OTD measurements are made from the same data collected during a certain period of time, whereby the same measurement data in a way is used two times in order to generate two different sets of measurement results. This saves the free time available during one frame, because it is not necessary to arrange separate measurement periods for the RSSI and the OTD measurements.

Abstract: A mechanism for synchronizing transmission of frames in a telecommunications network comprising a mobile station (MS), a radio network controller (SRNC), at least one base station (BS1, BS2). The mobile station (MS) and each base station (BS1, BS2) have a corresponding timing reference (MSFN, BSLFN, BS2FN). The mechanism comprises or performs the steps of 1) establishing a connection-specific timing reference (CFN) which is common to all nodes (MS, BS1, BS2, RNC) involved in the connection; 2) determining, for the base stations (BS1, BS2) an offset (OFS) between the timing reference of the base station in question and the CFN; and 3) using the offset (OFS) in the base stations (BS1, BS2), to compensate for the difference between the timing references.

Abstract: The object of the invention is a method to determine channel information in a cellular system, in which method user information is transmitted in information frames, which are transmitted by the current cell base station, and in which method neighbor cell base station information (105, 205, 305, 405, 505, 603, 612, 615, 622, 623, 632, 633) is received in order to synchronise to the neighbor cell base station. Preferably the method can be used to speed up or to enable the determination of channel information in connection with handover from the area of one base station to another. In the method according to the invention the user information transmission/reception is preferably interrupted during the reception (205, 305, 612, 632) of user information, which can be i.a. the signal level, the base station identity code (BSIC).

Abstract: An improved method for estimating the status of human physiological and/or psychological conditions by observing the values of the vocal tract parameters output from a digital speech encoder. The user (40) speaks to his device (41), which transforms the input speech from analog to digital form, performs speech encoding (42) on the derived digital signal, and provides values of speech coding parameters (43) locally for further analysis. The stored mathematical relation, e.g. the user-specific vocal tract transformation matrix (47) is retrieved from the memory and utilized in the calculation of corresponding condition parameters (45). Based on these calculated parameters, an estimation (48) of the present status of user's condition can be derived (48).

Abstract: When a mobile station (10) is in a DCCH camping state it monitors its assigned page frame. After making RSSI and possibly also Bit Error Rate/Word Error Rate (BER/WER) measurements the mobile station monitors the rate of change of the RSSI. If the rate of change is small and remains so, the mobile station is assumed to be in a stationary state. After determining that it is stationary, the mobile station may give an audible alert and/or display a message to request the user to confirm that the mobile station is (and will remain) stationary. When in the stationary state the mobile station inhibits making neighbor channel measurements for DCCH reselection. The mobile station continues to monitor its assigned page frame within an assigned digital control channel and to measure its own channel RSSI and possibly also the BER/WER. If these values subsequently indicate that the mobile station is no longer stationary, the mobile station immediately resumes all neighbor channel measurements.

Abstract: An interleaving process in which data is interleaved or interleaved data is de-interleaved. Input data units are distributed over a plurality of output groups of data units. In GSM telephony, input bits are distributed over nineteen transmission bursts. Incoming data units are written to a contiguous RAM and output groups are read from said RAM. Addressing circuitry controls the writing and reading to the RAM, such that data units are stored until required for an output group. After data has been read, these read locations are re-used for the storage of new input data, such that the duration over which a particular memory location stores a data unit depends upon the interleaving process delay for that particular data unit. The addressing circuitry includes modulo counters, each arranged to generate addressing signals for a respective set of memory locations within the RAM. Look-up tables are used to select modulo counts so as to provide conventional addresses to the RAM.
